Enum EthSnapMessage 

pub enum EthSnapMessage<N: NetworkPrimitives = EthNetworkPrimitives> {
    Eth(EthMessage<N>),
    Snap(SnapProtocolMessage),
}

A message carried by an EthSnapStream: either an eth message or a snap/2 message.

Variants

Eth(EthMessage<N>)

An eth protocol message.

Snap(SnapProtocolMessage)

A snap/2 (EIP-8189) protocol message.

Trait Implementations

impl<N: Debug + NetworkPrimitives> Debug for EthSnapMessage<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<St, N> Sink<EthSnapMessage<N>> for EthSnapStream<St, N>

where St: Stream<Item = Result<BytesMut>> + Sink<Bytes, Error = Error> + Unpin, N: NetworkPrimitives,

type Error = EthStreamError

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send( self: Pin<&mut Self>, item: EthSnapMessage<N>, ) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
